I am having issues with finishing the design for a JFET amp. I am only given the following:
Capacitors - 22uF
RG - 100K ohm
RL = 100K ohm
VDD - 15V
AV - 8 @ 1KHz
JFET - 2N5485
From the above I need to design the Amp and perform all of the calculations to find RD, RS1 and RS2 for the circuit diagram at the following link: **broken link removed**
The issue that I am having is that I can't seem to figure out the RD without knowing the RS values and vice versa.
Please show me the method I should use to find these values. So far my class has been stumped and we weren't able to get any method that works from our professor. The method he used turned out to not work (by his own admission) and he never offered up another method or the actual values that we should end up with. We were only told that the actual values should be different for each person because JFETS don't all share the same Q-Points.
Thanks in advance for any help that anybody can offer. Please let me know if you need more clarification, but I'm not sure I have much more to give as that is about all that is on my sheet.
